Limiter ​

Signal limiter that constrains input values between specified boundaries.

Implements a hard saturation that restricts the output signal to remain within the bounds specified by y_min and y_max. When the input signal is within these limits, it passes through unchanged; otherwise, the output is clamped to the nearest limit value. This is commonly used in control systems to prevent signals from exceeding safe operating ranges.

SISO

Usage ​

Limiter(y_max, y_min=-y_max)

Parameters: ​

NameDescriptionUnitsDefault value
y_maxMaximum allowed output value–
y_minMinimum allowed output value, defaults to negative of y_max–-y_max

Connectors ​

  • u - This connector represents a real signal as an input to a component (RealInput)

  • y - This connector represents a real signal as an output from a component (RealOutput)

Behavior ​

y(t)=clamp(u(t),y_min,y_max)
